If you thought that sequins only was to wear in winter, I have to correct you. Black sequins does actually look nicest in the darker months but style is all about breaking the rules. Sequins in metallic and gold looks perfect on your summer tanned skin. Let the sequined piece be the focus of your outfit and leave everything else neutral.
